Problem: You need to write/draw something on a dry-erase board many times.
Solution:
My solution would be a Dry erase stamp. Basically, this would be a rubber stamp (baked) of what you are writing (backwards of course), and an ink pad that has dry-erase ink.
Problems with the solution:
First:
Dry erase ink dries very quickly. In order to make an ink pad with it, it would have to stay wet longer.
Second: If you don't have a stamp of what you need to put on the board, you have to write it. This could be solved by using something like the half-baked "Dynamic Stamp" (link) so you could design on the computer, add dry erase ink, and stamp as needed.

I like it, certainly something that couldn't
be done with a regular chalkboard. It
makes sense. + |
|
| |
I don't think having to stop and pick up a stamp or to make one would save you any time. |
|
| |
If you made this into a roller, I could draw plasma membranes very easily. |
|
| |
It could be a roller, for patterns or funny lines. |

Came here because I just thought of this myself, could the alternative be wet erase then? Is that ink any better for the purpose? I was thinking of it for a couple of applications: |
|
| |
1) for a board game, you could have a shiny mat that you need to stamp things on in place of having say cards or or tiles |
|
| |
2) in jr. high, my science teacher would make elaborate chalk drawings that we'd get to see when we entered class. you can do that on white boards, but it could be made easier with standard stamps, like leaves, flowers, borders, etc. |

Also, maybe if the dry erase ink evaporates too fast, then perhaps a "shaped pen" might work instead? |
|

//Dry erase ink dries very quickly//
Make the "stamp" out of reasonably dense foam rubber or similar, already soaked with the liquid that evaporates too fast. Then coat with (dunk? pad?) the normal dry-erase ink onto it prior to stamping; it will stay wet until mushed onto the surface. |
|
| |
//couldn't be done with a regular chalkboard// Why not? You can get "liquid chalk" which I presume is chalk powder in suspension in an evaporateable liquid. |

Is it just me or are white-boards horrible? Does anyone else miss traditional blackboards? |
|
| |
And don't get me started on those giant computer screens that they use instead of write-on boards. |
